III. Exemplary System Operation

Reference will now be made to FIGS. 5-6. FIGS. 5-6 illustrate operationsand processes that can be performed for providing weather-relatedmaintenance services, such as dispensing travel path applicants, fortravel paths in geographic areas.

A. Geographic Areas

In one embodiment, maintenance vehicles 100 may be associated with,assigned to, or traverse one or more geographic areas. In oneembodiment, the geographic areas may correspond to countries, regions,states, counties, cities, towns, and/or the like. For example,geographic areas may be defined around the United States, the state ofGeorgia, Gwinnett County in the state of Georgia, and/or the like. Inone embodiment, the geographic areas may correspond to travel paths(e.g., roads, avenues, highways, streets, toll roads, ways, interstates,bridges, freeways, etc.). For example, a geographic area may be definedaround a public road (e.g., substantially around I-285) or a portion ofa public road (e.g., exit and/or entrance ramps on I-75 in Georgia orthroughout the U.S. and portions of I-75 with a grade above 20%). Aswill be recognized, geographic areas may also correspond to private landareas, vehicle staging areas, parking lots (e.g., at malls or otherestablishments), driveways, and/or the like.

According to various embodiments of the present invention, a geographicarea may overlap or reside wholly within another geographic area.Geographic areas may, for example, be as large as an entire country,region, state, county, city, or town (or larger). According to variousembodiments, the geographic areas need not be continuous. In otherwords, a geographic area may specifically exclude an area that wouldotherwise fall within the geographic area (e.g., such that thegeographic area forms a donut or other shape around the excluded area).

The geographic areas may be defined based on any number and/orcombination of factors including, but not limited to, those describedabove. The foregoing examples are therefore provided for exemplarypurposes only and should not be taken in any way as limiting embodimentsof the present invention to the examples provided.

B. Weather-Related Maintenance Services for Travel Paths in GeographicAreas

As indicated, various weather-related maintenance services can beprovided for travel paths. The weather related maintenance services mayinclude maintenance vehicles 100 dispensing travel path applicants on,for example, snowy and/or icy travel paths. Such travel path applicantsmay be used to melt ice or snow, prevent the accumulation of ice orsnow, and/or improve traction for vehicles. To do so, travel pathapplicants may be in a variety of forms, such as sand, cinders, slag,bottom ash, liquid chemicals (e.g., magnesium chloride, calciumchloride), salt, rock salt, and/or salt brine. As will be recognized, avariety of travel path applicants can be used to adapt of various needsand circumstances.

In one embodiment, travel path applicants can be dispensed at a varietyof dispense rates. For example, illustrative dispense rates may bebetween 50 and 900 pounds of travel path applicant per travel path mile.Similarly, a variety of different dispense patterns can be used todispense travel path applicants on a travel path. For instance, travelpath applicants may be dispensed in various patterns ranging from, forexample, 5 feet to 90 feet. In various embodiments, by adjusting thedispense rates and the dispense patterns, waste of dispensed travelapplicants can be minimized.

As will be recognized, the dispense rate and/or dispense pattern oftravel path applicants dispensed may vary based on the characteristicsof the travel path (or parts of the travel path). For example, parts oftravel paths having one or more of the following characteristics maybenefit from increased dispensing of travel path applicants: bridges;school zones; intersections; high-traffic areas; curves or turns;high-accident areas; travel path grades above a certain percentage,degree, or grade; increased travel speeds; certain types of pavement(e.g., pervious concrete, asphalt); and/or the like. For instance,travel paths with grades above 20% may have a greater amount of travelpath applicants dispensed on the parts of the travel path that havegrades of 20% or above. As will be recognized, various othercharacteristics can be used to adapt to various needs and circumstances.

In one embodiment, a variety of different approaches can be used todispense travel path applicants.

C. Telematics-Based Dispensing

In one embodiment, telematics data may be used to dispense travel pathapplicants on a travel path. For example, a computing entity (e.g., thedata collection device 130, portable device 105, and/or server 110) maybe configured to collect and analyze telematics data. As indicated,telematics data may include latitude, longitude, altitude, geocode,course, position, time, speed, traction (e.g., tire slippage),acceleration, engine torque, gyroscope, emissions, RPM, tire pressure,oil pressure, seat belt usage, distance, fuel, idle, air quality,temperature, meteorological data, and/or the like. Using such telematicsdata, the maintenance vehicle 100 can be used to dispense travel pathapplicants under certain conditions.

i. Thresholds

In one embodiment, one or more thresholds can be defined to control thedispensing of travel path applicants. Further, each threshold may beassociated with a dispense rate and/or a dispense pattern. For example,three different speed thresholds may be defined: (1) less than or equalto 20 miles per hour; (2) above 20 miles per hours and less than orequal to 40 miles per hour; and (3) above 40 miles per hour. Each ofthese thresholds may be associated with a dispense rate and/or adispense pattern. For example, the first threshold ((1) less than orequal to 20 miles per hour) may be associated with a dispense rate of200 pounds of travel path applicant per travel path mile. Similarly, thesecond threshold ((2) above 20 miles per hours and less than or equal to40 miles per hour) may be associated with a dispense rate of 275 poundsof travel path applicant per travel path mile. And the third threshold((3) above 40 miles per hour) may be associated with a dispense rate of350 pounds of travel path applicant per travel path mile. Thus, when themaintenance vehicle 100 travels at the various speeds, the travel pathapplicant can be dispensed at the appropriate dispense rate (and/ordispense pattern).

As will be recognized, a variety of other thresholds can be defined andassociated with dispense rates and/or dispense patterns. Such thresholdsmay include engine torque thresholds: (1) less than or equal to 300pound-feet of torque and (2) above 300 pound-feet of torque. Additionalthresholds may include one or more traction thresholds (e.g., tireslippage), and/or one or more acceleration thresholds. Further, onegyroscope thresholds can used: (1) an inclination angle of a maintenancevehicle 100 less than or equal 20% with respect to the horizontal lineand (2) an inclination angle of a maintenance vehicle 100 above 20% withrespect to the horizontal line. This particular threshold can be used todispense travel path applicants based on the grade of the travel path.In one embodiment, each of these thresholds may be associated withdispense rates and/or dispense patterns.

In one embodiment, multiple thresholds can be defined to control thedispensing of a travel path applicant, such as shown below in Table 1.

TABLE 1 TRAVEL PATH GRADE SPEED 20% grade ≤ >20% grade   20 mph ≤ 200275 >20 mph and ≤40 mph 275 350 >40 mph 350 425

As will be recognized, various thresholds can be defined to adapt tovarious needs and circumstances. To determine whether such thresholdshave been satisfied, telematics data can collected and analyzedregularly, periodically, continuously, and/or in response to certaintriggers.

ii. Regular, Periodic, and/or Continuous Collection

In one embodiment, as indicated in Block 500 of FIG. 5, a computingentity (e.g., the data collection device 130, portable device 105,and/or server 110) may be configured to regularly, periodically, and/orcontinuously collect and analyze telematics data. For example, acomputing entity (e.g., the data collection device 130, portable device105, and/or server 110) can be configured to regularly, periodically,and/or continuously collect and analyze telematics data as a maintenancevehicle 100 travels in (e.g., traverses) a geographic area. Forinstance, telematics data can be collected and analyzed at certain timeintervals (such as every 2, 5, 15 seconds) and/or certain distanceintervals (such as every 1/10, ⅕, ½ mile).

iii. Triggered Collection

As indicated in Block 500 of FIG. 5, telematics data can be collectedand analyzed as maintenance vehicles 100 are operated in geographicareas, such as while maintenance vehicles 100 are traversing travelpaths and/or dispensing travel path applicants. To do so, in oneembodiment, a computing entity (e.g., a data collection device 130,portable device 105, and/or server 110) can be configured to collect andanalyze telematics data in response to (e.g., after) one or morepredefined triggers. Continuing with the above example, a computingentity can collect and analyze telematics data once the maintenancevehicle begins dispensing travel path applicants, for example. Thus,various triggers can be defined for telematics data collection andanalysis. Such trigger events may include, but are not limited to: (1)traveling above or below a certain speed; (2) traveling within ageofenced area; and/or (3) the like. Thus, in response to (e.g., after)one or more predefined trigger events, a computing entity (e.g., thedata collection device 130, portable device 105, and/or server 110) cancollect and analyze telematics data as a maintenance vehicle travels in(e.g., traverses) a geographic area

iv. Dispensing

After (e.g., in response to) telematics data is collected regularly,periodically, continuously, and/or in response to certain triggers, acomputing entity can analyze the telematics data to determine whetherone or more of the thresholds have been satisfied.

In one embodiment, in response to (e.g., after) a determination that oneor more thresholds have been satisfied (Block 505 of FIG. 5), acomputing entity (e.g., the data collection device 130, portable device105, or server 110) can automatically adjust the dispensing of thetravel path applicant (Block 510 of FIG. 5). For example, afterdetermining that the travel path grade is >20% and that the maintenancevehicle is travel 35 miles per hours, a computing entity (e.g., the datacollection device 130, portable device 105, or server 110) canautomatically adjust the dispensing of the travel path applicant to 350pounds of travel path applicant per travel path mile. In anotherembodiment, satisfying the one or more thresholds may be used toinitiate (or stop) the dispensing of travel path applicants.Additionally or alternatively, the computing entity can alsoautomatically adjust the dispense pattern of the travel path applicant.In still another embodiment, instead of (and/or in addition to)automatically adjusting the dispensing, the computing entity canindicate (e.g., visibly or audibly) to the driver of the maintenancevehicle 100 that he or she should adjust the dispensing of the travelpath applicant to the specified dispense rate and/or pattern. As will berecognized a variety of other approaches and techniques can be used toadapt to various needs and circumstances.

D. Geofence-Based Dispensing

In one embodiment, one or more geofences may be used to dispense travelpath applicants on a travel path.

i. Defined Geofences

Map vendors, such as Tele Atlas® and NAVTEQ®, provide digitized maps toa variety of clients for different purposes. For example, such companiesmay provide digitized maps to: (a) Internet websites for providingdriving directions to consumers; (b) cellular companies to include inphones and personal digital assistants; (c) government agencies (e.g.,the United States Department of Agriculture and Environmental ProtectionAgency) for use in their respective government functions; and (d)transportation and logistics companies. In one embodiment, entities thatdispense travel path applicants, can license, purchase, and/or usedigitized maps from vendors like Tele Atlas® and NAVTEQ®.

In one embodiment, using such digitized maps, a computing entity (e.g.,the data collection device 130, portable device 105, and/or server 110)may be used to define one or more geofences. The geofences may bedefined to surround countries, regions, states, counties, cities, towns,neighborhoods, off-road areas (e.g., areas without paved roads), privateland areas, parking lots, and/or the like. Further, one or moregeofences may be defined to surround travel paths (e.g., roads, avenues,highways, streets, toll roads, ways, interstates, freeways) or parts oftravel paths (e.g., such as bridges, school zones, intersections, exitand entrance ramps, grades above a certain percentage, high-trafficareas, high-accident areas, increased travel speed areas, travel pathswith certain types of pavement, and/or the like). The geofences may bedefined, for example, by the latitude and longitude coordinatesassociated with various points along the perimeter of the geographicarea. Alternatively, geofences may be defined based on latitude andlongitude coordinates of the center, as well as the radius, of thegeographic area. Geofences may be as large as an entire country, region,state, county, city, or town (or larger) or as small as an intersection(or smaller). The geographic areas, and therefore the geofences, may beany shape including, but not limited to, a circle, square, rectangle, anirregular shape, and/or the like. Moreover, the geofenced areas need notbe the same shape or size. Accordingly, any combination of shapes andsizes may be used in accordance with embodiments of the presentinvention.

In one embodiment, once at least one geofence has been defined, thecoordinates (or similar methods for defining the geofenced areas) may bestored in a database associated with, for example, the data collectiondevice 130, portable device 105, and/or server 110. Thus, as themaintenance vehicle 100 enters and exits the one or more definedgeofences, a computing entity (the data collection device 130, portabledevice 105, and/or server 110) can monitor the location of themaintenance vehicle 100 and trigger/initiate certain events based on themaintenance vehicle's 100 location. For instance, entering and/orexiting a geofenced area may be used to adjust the dispense rate and/ordispense pattern of travel path applicants as the maintenance vehicletraverses a travel path within a geographic area. In one embodiment, todo so, each geofenced area may be associated with one or more dispenserates and/or one or more dispense patterns. For example, a geofencedefined around a bridge, intersection, or a part of a travel path with agrade above 20% may be associated with a dispense rate of 450 pounds oftravel path applicant per travel path mile. Whereas a geofence definedaround a straight part of a lightly-traveled travel path may beassociated with a dispense rate of 150 pounds of travel path applicantper travel path mile. Similarly, dispense patterns can be associatedwith each defined geofence.

ii. Dispensing

In one embodiment, after the one or more geofenced areas (e.g.,geofences) have been defined, the location of the maintenance vehicle100 can be monitored (Block 600 of FIG. 6) on a regular, periodic, orcontinuous basis. Generally, the location of the maintenance vehicle 100can be monitored by any of a variety of computing entities (e.g., thedata collection device 130, portable device 105, and/or server 110),including the data collection device 130, the portable device 105,and/or the server 110. For example, as noted above, the maintenancevehicle's 100 location at a particular time may be determined with theaid of location-determining devices, location sensors 120 (e.g., GNSSsensors), and/or other telemetry location services (e.g., cellularassisted GPS or real time location system or server technology usingreceived signal strength indicators from a Wi-Fi network). By using themaintenance vehicle's 100 location, a computing entity (data collectiondevice 130, portable device 105, or server 110) can determine, forexample, when the vehicle 100 enters a defined geofence (Block 605 ofFIG. 6).

In one embodiment, as indicated in Block 610 of FIG. 6, in response to(e.g., after) a determination that a maintenance vehicle 100 has entereda defined geofenced area, a computing entity (e.g., the data collectiondevice 130, portable device 105, or server 110) can automatically adjustthe dispensing of the travel path applicant. For example, upon enteringa geofenced area, such as a geofence defined around an intersectionassociated with a dispense rate of 450 pounds of travel path applicantper travel path mile, a computing entity can automatically adjust thedispense rate of the travel path applicant to 450 pounds per travel pathmile. In another embodiment, entering the geofence may be used toinitiate (or stop) the dispensing of a travel path applicant.Additionally or alternatively, the computing entity can alsoautomatically adjust the dispense pattern of the travel path applicant.In still another embodiment, instead of (and/or in addition to)automatically adjusting the dispensing, the computing entity canindicate (e.g., visibly or audibly) to the driver of the maintenancevehicle 100 that he or she should adjust the dispensing of the travelpath applicant to the specified dispense rate and/or pattern.

In one embodiment, after the maintenance vehicle 100 has entered thegeofenced area, the location of the vehicle 100 can continue to bemonitored (Block 615 of FIG. 6) by any of a variety of computingentities on a regular, periodic, or continuous basis. By using themaintenance vehicle's 100 location, a computing entity can determine,for example, when the maintenance vehicle 100 exits the definedgeofenced area (Block 620 of FIG. 6). As described, this may includeusing location-determining devices, location sensors 120 (e.g., GNSSsensors), or other telemetry location services (e.g., cellular assistedGPS or real time location system or server technology using receivedsignal strength indicators from a Wi-Fi network).

In one embodiment, as indicated in Block 625 of FIG. 6, in response to(e.g., after) a determination that a maintenance vehicle 100 has exitedthe defined geofenced area, a computing entity can automatically adjustthe dispensing of the travel path applicant. For example, upon enteringa geofenced area, such as a geofence defined around a straight part of alightly-traveled travel path associated with a dispense rate of 50pounds of travel path applicant per travel path mile, the computingentity can automatically adjust the dispense rate of the travel pathapplicant to 50 pounds per travel path mile. In another embodiment,exiting the geofence may be used to stop (or initiate) the dispensing oftravel path applicants altogether. Additionally or alternatively, thecomputing entity can also automatically adjust the dispense pattern ofthe travel path applicant. In still another embodiment, instead of(and/or in addition to) automatically adjusting the dispensing, thecomputing entity can indicate (e.g., visibly or audibly) to the driverof the maintenance vehicle 100 that he or she should adjust thedispensing of the travel path applicant to the specified dispense rateand/or pattern. As will be recognized a variety of approaches andtechniques can be used to adapt to various needs and circumstances.
